So the Greatest Common Divisior 119, 551, 21 is 1.

Therefore, GCD of numbers 119, 551, 21 is 1

Given Input Data is 119, 551, 21

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 119 is 7 x 17

Prime Factorization of 551 is 19 x 29

Prime Factorization of 21 is 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(119, 551) = 65569

GCD(119, 551) = ( 119 x 551 ) / 65569

GCD(119, 551) = 65569 / 65569

GCD(119, 551) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

GCD of 119, 551, 21 is 1
